IMPROVEMENT IN SUGAR-CANE PRESSES.

Specification forming part of Letters Patent No. 24,789, dated July 19,1559.

lo @ZZ whom t may coli/cern.-

Be it known that I, WILLIAM BULL, of N ew California, in the county ofGrant and State ot'XVisconsin, have invented a new and Improved Pressfor Expressing the Juice from Sugar-Gane; and I do hereby declare thatthe following is a full, clear, and exact description of the saine,reference being had to the annexed drawings, making a part of thisspecilication, in Which Figure l is an end view of my invention inelevation, Fig. 2, a vertical section of the same, taken in the line xx, Fig. l.

Similar letters of reference indicate correspending parts in the twoIigures.

To enable those skilled in the art to l'ully understand and construct myinvention, I will proceed to describe it.

A represents a suitable framing, in the up per part of which a shalt, B,is placed in stationary bearings a. On the shalt B two iiywheels, C C,are placed, and also a roller, D, the latter being of metal or wood,cast metal being preferable, and having a flange, b, at each side of it,as shown clearly in Fig. l. On the lower' part of the framing A, andbetween the two liy-wheels C C, a frame, E, is placed and secured at itsfront end by'hinges c. On the back part of the framing A, and below theframe E, a Wedge, F, is placed, by adjusting which. the back part of theframe E may be elevated or depressed at pleasure. To the under side ofthe frame E a pan or reservoir, G, is secured, having a discharge-spout,II, attached. On the frame E a shaft, I, is placed, said shaft having aroller, J, placed on it, which ts between the flanges I) b of the rollerI), as shown clearly in Fig. l. rIhe two shafts are connected by toothedwheels K K. To

the frame E two inclined troughs or spouts, L L', are attached, saidtroughs or spouts being in the same inclined plane and placed at opposite sides of the rollers, aid in line with their bitc.7 (See Fig. 2.)

rI`he operation is as follows: Motion is given the shaft B in any properway, either by hand or other power, and the cane is placed on the moreelevated trough or spout L, and passes between the rollers D J, whichrotate in the direction indicated by the arrows. The juice is expressedfrom the cane by the pressure of the rollers D J, the crushed canepassing down the spout L and lthe juice falling into the reservoir G,from which it is discharged through the spout H. The pressure of therollers on the cane is graduated by ad justing the wedge F. l

This machine may be constructed at a very small cost. It has beenpractically tested and operates very successfully, and is well adaptedfor expressing the juice from the Chinese cane, 7 (Sorghmn scccharcmn.)

I do not claim, broadly, the employment or use of pressure-rollers, forthey have been long used for similar or analogous purposes; but,

Having thus described my invention, what I do claim as new, and desireto secure by Letters Patent, is"

The arrangement and combination of the hinged adjustable frame E, rollerJ, frame A, wedge F, inclined spouts L L', and roller I), as and for thepurpose herein shown and described.

VILLIAM BULL.
